Were two contestants on The Block NZ were caught HOOKING UP?

A PR insider from the MediaWorks television show has confirmed that two members from rival teams were caught snuggling up under the covers.

TV3 is remaining tight-lipped over who exactly was involved in the "snuggling" - but the identities won't stay hidden for long, as the footage will screen in an upcoming episode this week.

"There is no doubt having friends as teammates, rather than couples, has changes the dynamic on set this year," an insider said.

"They're a very social bunch and understandably they have become close through this shared experience. I can imagine there have been some cold nights on set while we're mid-build so I guess anything could happen."
